On the problem of setting working time in the implementation of Gantt chart.

I need to specify the tasks in each time period, as shown in the following figure:

Can it be realized?
All help and info is greatly appreciated.

Unfortunately, there is no such built-in view. You can try using gantt.groupBy. With the help of grouping, you can create a separate grouping task for each day. There is an example that shows the concept of a solution, but it needs improvement: https://snippet.dhtmlx.com/5141cdgq. Click on the “Group by date” button in the upper left corner of the example to see the result of the grouping.
You might find gantt.addCalendar useful, which allows you to add a separate calendar for each task.
Here is an example in the snippet: https://snippet.dhtmlx.com/26sjp2tl.
